The management of irreducible atlantoaxial dislocation associated is challenging. Direct posterior distraction technique we proposed in 2010 could achieve satisfactory reduction. In 2020, we modified this technique and proposed a posterior intra-articular distraction technique. The intra-articular distraction technique could theoretically achieve satisfactory reduction and fusion. However, its superiority has not been proven. Therefore, we design a prospective study to compare the reduction rate and fusion rate of different strategies.
